Regarding the sem_post problem, here is an old email from Tomasz Gebarowski which is interesting because it states that he had a sem_post issue with cdp.so which he solved by modifying the modules/cdp/Makefile. Now if we skip forward to right now, I notice that cdp.so COMPILE and LINKS for me with no errors and I also notice that Tomasz' fix is in place, but other ims modules that also use semaphore do NOT link properly for me in ubuntu and are exhibiting the same *undefined symbol: sem_post* error Tomasz had years ago in his ubuntu compiles. I think (hope) this may be more than coincidence that these things are related??? I have tried Tomasz' fix with an ubuntu compile but I still get the sem_post error. I still think he is on to something here and I am NOT modifying the Makefile correctly. Any suggestions on specifics to test this theory are greatly welcome. Here is Tomansz' email..... ---------------------------------------------------------------------------------------------------------------------- https://lists.berlios.de/pipermail/openimscore-users/2011-December/007219.ht... [OpenIMSCore-Users] PROBLEM WITH ICSCF AND SCSCF STARTING Tomasz Gebarowski gebarowski at gmail.com Thu Dec 29 22:19:55 CET 2011 Previous message: [OpenIMSCore-Users] Fwd: How are you... Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hello, I've just googled some old post from October 2011, describing an issue with crashing I-CSCF and S-CSCF. The log message was something like:

0(2142) ERROR: load_module: could not open module /opt/OpenIMSCore/ser_ims/ modules/cdp/cdp.so>: /opt/OpenIMSCore/ser_ims/modules/cdp/cdp.so: undefined symbol: sem_post

I managed to fix this issue on Ubuntu 11.10. It seems that UBUNTU, required linking cdp.so against pthread. Below you can find a simple patch:
